      "geoname_id": 6255147,
      "name": "Asia"
    },
    "country": {
      "geoname_id": 1861060,
      "iso_code": "JP",
      "name": "Japan"
    },
    "location": {
      "latitude": 35.69,
      "longitude": 139.69,
      "time_zone": "Asia/Tokyo"
    },
    "autonomous_system": {
      "number": 2516,
      "organization": "KDDI CORPORATION"
    }
  }
